Randomly noticed this:

export const e164: RegExp = /^\+(?:[0-9]){6,14}[0-9]$/;

This allows phone numbers like +000000000 that are invalid.

Maybe /^\+[1-9]\d{6,14}$/ would be better.

I don't think that the reference is explicit on this, but there are no country codes starting with 0.

Happy to send a PR if you think this could be improved in Zod v4.
